“Again, if the world is destroyed, it must needs either be destroyed according to nature or against nature. Against nature is impossible, for that which is against nature is not stronger than nature. If according to nature, there must be another nature which changes the nature of the world: which does not appear.”
XVII. That the World is by nature Eternal.

Part 2: Metaphysical Rebellion
The Rebel (1951)
Context: The ancients, even though they believed in destiny, believed primarily in nature, in which they participated wholeheartedly. To rebel against nature amounted to rebelling against oneself. It was butting one's head against a wall.

A note on this statement is included by Stillman Drake in his Galileo at Work, His Scientific Biography (1981): Galileo adhered to this position in his Dialogue at least as to the "integral bodies of the universe." by which he meant stars and planets, here called "parts of the universe." But he did not attempt to explain the planetary motions on any mechanical basis, nor does this argument from "best arrangement" have any bearing on inertial motion, which to Galileo was indifference to motion and rest and not a tendency to move, either circularly or straight.
